I have a 14/16 cat with Jaws pipe and an 18 and 19.
Ctec hands down!
I loved the zuke from 2008-2017. Ctec runs so clean and crisp all the time and clutching is spot on. Belts last thousands of miles instead of hundreds.

i also agree. I had a zuke that was basically a 2016, belt drive, carbon hood/skid, full pipe set, fuel controller etc etc and my 18 feels even better. runs so much smoother, clutching far superior, fit and finish better (minus the intake gaps that I had to fix), panels much nicer, led headlight is awesome etc etc
